According to Roesler and Barnard (Optical proxy for phytoplankton biomass in the absence of photophysiology: Rethinking the absorption line height, Methods in Oceanography, 2013), “absorption meters are highly prone to biofouling, particularly biofilms which not only attenuate the collimated beam but also impact the scattering properties of the optical surfaces and tubes. In productive coastal waters biofouling can have significant impacts (i.e. 10% of the signal) within one to two weeks”.

There is no pressure variable in the .nc files. This should be a coordinate.

wavelength_a and wavelength_c are arrays of fill values for deployments 7 and 8. These variables should contain the measurement wavelengths.

beam_attenuation and optical_absorption are arrays of fill values for deployments 2, 3 and 6.

Deployment: 2

Annotation ID 709 "Short deployment due to the fuel cell not functioning correctly" should be updated to indicate that this refers to deployment 2, and data aren't expected from most instruments for this time period.

Per vendor feedback, the first 1-2 min of each AC-S instrument sampling period should be considered suspect. Signal drift can occur as the instrument warms up, flushes with seawater, and the filter wheel spins up.
